How do you program keyless entry?
The factory master code cannot be reprogrammed...however you can program a personal code that is easier to remember. on my 2003 this is the procedure: 1. enter the 5 digit master code. 2. press 1/2 3. enter your own 5 digit code. 4. lock the vehicle. 5. test your new code. I removed the master code from my vehicle so that it can't be copied by the guy at the local car wash or local garage.
